Have ordered one. Should I run seperate contactors for the heating and cooling? For simplicity my mind says no, but my electrical engineering background says yes.

I have currently borrowed the bosses cellar controller and have a st1000 ordered.

I just ordered an STC1000 also. I am planning so far on a small industrial 200watt heater off of the internal heat contact. I havent read every page in this thread but have read a few that are running a small freezer right off the STC1000. A separate contactor would protect the temp controller though from the starting current of a compressor motor. I would feel better about a separate relay on the cooling side anyway.

I think the internal relays are rated at 10A? Chances are you'll be fine without an external contactor relay. Since this unit is so cheap, to be honest it'll be cheaper to replace the STC-1000 than buy separate contactors or SSRs.

Indeed, I run a 7 cu foot chest freezer off mine.

I think they are rated at 10A, but if you open it up you will likely find the relays are marked 15A.

Also depends how much current the solder traces on the board can handle, and what the rating is on those screw terminals. For a typical refrigerator or chest freezer load I wouldn't worry about it, but if you were going to run a 1500 watt heater off it for some reason I'd probably go with a separate contactor or SSR.

This might be a dumb question lol. But i havent seen it in the pages ive looked through yet. If you rig one of these up to a stand-up fridge, will the top freezer portion still be able to function?

Yeah, because you're plugging the whole fridge into the outlet installed in the box, just like you would with plugging it into the wall. But, the caveat is that while the freezer will be powered when the fridge is powered, at proper Ale fermentation temps that will mean the freezer will stay ABOVE freezing. It will be slightly cooler than the fridge, perhaps, but unless you're doing a lager, it won't be freezing in the freezer...

so maybe that means, No, it won't "work", at least not as it normally would.

Ie. setting the temp probe to 64 and placing it in the fridge portion would mean the freezer is probably in the 40's. Setting the fridge to 40 means the freezer is below 32.

When I cold crash around 40, my freezer frosts over. When I ferment, though, it's not frosty.

Right, the freezer section will work, but it's probably not like you want to trust it for keeping meat in there or anything. The temp would not be very predictable if you are controlling the fridge temp to 60F or whatever your setpoint is.

The STC-1000 imho is best used on 'old school' refrigerators that don't have fancy electronic controls or auto defrost.
